No. They say up to 40 miles. Unfortunately, it is bunk. Those are a two watt radio. In perfect conditions with clear sky and one person on top of a mountain and the other clearly in the open, it is slightly possible to get 40 miles. But remember, the earth is round, not flat. Every 22.5 miles the earth "curves" making flat, straight communication impossible. What is the minimum distance you will accept and determine if that is enough before returning them. Even moving up to business band 5 watt handheld radios will never get a long range. I use mine as an wireless intercom. I never expect even two miles.This applies to any brand, so don't be fooled.
